This mod sets the build time of every station module to 60 seconds. Works on Win7. Save safe; a station built with this mod should not change if you remove the mod.
Ongoing builds will use the build time that was in effect when the build started; but the next module built will use the new time.
You might also find FreeBuilder useful; it fills player owned build storage with whatever it wants as soon as it orders it. No waiting for materials to arrive.
